Trichotillomania cover up

So this is quite a big step for me. I appreciate not everyone is interested or in a position to help, but thank you to anyone who takes the time to read.

Since I was 14, I've suffered with trichotillomania. This was brought on by the sudden death of my stepfather in a car crash, who had been the only father figure I had known.

It started with my eyelashes. I remember vividly being on a flight to Mallorca with my mum and my 2 little brothers the year after my stepfathers death. It began with playing with them, and one of my eyelashes coming out. By the time the flight had ended, I had pulled all of the eyelashes out of my left eye. By the end of my holiday, the right eye was gone too. Within 2 or 3 months my mum noticed my shed becoming 2 centimetres wide, and noticed bald patches. Soon after, she put 2 and 2 together and realised something was very wrong.

So as a consequence, since the age of 14, I've suffered with being bald. The loss of friends and bullying that followed made my teenage years pretty difficult, and my self confidence was non-existent. I didn't know what was wrong with me, what I was doing or why. I had no idea if I was just crazy or if I was just self harming. I didn't know what the condition was called until a few years later when I watched an episode of Scrubs.

Several years ago, I discovered a system that could be used over what little hair I had to help cover this baldness. As cliché as this sounds, it changed my life. I'm a completely different person. I take pride in how I look, I'm outgoing, I'm confident and I'm happy. The fabric system uses clips on what little hair I have to hold the mesh in place, and extensions are sewn on top of this.

Unfortunately, the system I do currently have is now becoming too worn to use and I'm unable to afford the cost required replace it. Due to an ongoing disability, I only work 16 hours a week and can earn limited money. As hard as it is to admit to the condition and to explain my situation, any help you can provide would be appreciated.

However, I am also wondering if anyone knows any cheaper alternatives? I have tried wigs and these were extremely uncomfortable and irritated my scalp unbearably.
